Abstract: To provide a method of processing a tempered glass in which a length of time required for manufacturing one plate of a product glass is significantly reduced while the quality of the product glass is secured. In the method of processing the tempered glass in which a stacked block (1a) acting as a chemical tempered glass (1) is processed by using a processing device (8) under a condition that the processing device (8) is rotated and vibrated, the stacked block (1a) is cut out from a stack (1A) acting as the chemical tempered glass (1) by using a dicing blade (84), prior to the processing of the stacked block (1a) by using the processing device (8), and a finishing to an outer periphery of the stacked block (1a) is also performed during the processing of the stacked block (1a) by using the processing device (8).

Abstract: The processing device has a shaft shape, at least an outer surface of a front end which is a surface of holding diamond grind grains, and a concave portion formed on a central part in a radial direction of a front surface. The chemical tempered glass having a surface reinforced layer is processed by using the processing device which is rotated around its shaft center and vibrated in a direction of extending the shaft center. The vibration of the processing device is feed-back controlled to the chemical tempered glass to approach an amplitude and a frequency of the processing device to a target amplitude and a target frequency, respectively, and setting the target amplitude at a value in a range from 3 ?m to 9 ?m and the target frequency at a value in a range from 60 kHz to 64 kHz.

Abstract: To provide a method of processing a tempered glass in a simple and appropriate manner while a degree of freedom of processing is secured. Vibration of the processing device is controlled in a feedback fashion such that a vibration amplitude and a vibration frequency of the processing device approach to a target vibration amplitude and a target vibration frequency not to keep them in a range where a value of worsening the quality is generated. Further, a specified sample cycle of 0.3 msec or less in the feedback control is employed.
